This vulnerability (CVE-2026-39790) affects VikRentCar versions up to 1.4.6 and is caused by improper neutralization of input during web page generation, enabling unauthenticated Cross-Site Scripting (XSS) attacks. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No vendor advisory or patch information is available to confirm remediation status.

Successful exploitation could allow an unauthenticated attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to limited disclosure of information, modification of data, and partial disruption of service. The attack requires user interaction and affects confidentiality, integrity, and availability at a low level.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider applying input validation and output encoding as temporary mitigations to reduce XSS risk.
